COMPOSITE POWDER PHOTOCATALYST AND METHOD FOR PRODUCTION THEREOF Russian patent published in 2024 - IPC B01J21/06 B01J23/06 B01J23/20 B01J37/04 B01J37/34 C02F1/00 

FIELD: production of composite materials.

SUBSTANCE: invention relates to materials for catalysis and technology of producing catalysts for environmental application, specifically for catalytic photodegradation of organic and inorganic compounds in solutions, for example, for photodegradation of waste water. Described is a composite powder photocatalyst for catalytic photodegradation of organic and inorganic compounds in waste water, containing carrier particles with metal oxides, wherein it contains carrier metals Zn, Ti and oxides ZnO, TiO₂, Nb₂O₅ with the following content of elements (at.%): Zn—40–42; Ti—3–5; Nb—1–2; O—50–55. To obtain a composite powder photocatalyst, initial powders of the composite are processed in the anode region of the plasma generator using a plasmatron with vortex stabilization and an expanding channel. Initial powders used are a thoroughly mixed mixture of micropowders of metals Zn, Ti, Nb, taken in ratio Zn—82–84 at.%; Ti—15–16 at.%; Nb—1.5–2.5 at.%; which is fed into plasmatron with flow of inert gas.

EFFECT: creation of a catalyst with high photocatalytic activity.
